Review: Philips' Latest Sonicare FlexCare Platinum Brush Connects to Your iPhone via Bluetooth

Philips recently announced its first Bluetooth-connected Sonicare toothbrush aimed at adults, which interfaces with an iPhone to monitor brushing habits, offer brushing tips, and make sure you're brushing right.

Priced at $199, the Sonicare FlexCare Platinum Connected takes the well-known and popular FlexCare brush and introduces iPhone connectivity through a Sonicare app that tracks everything from how long you brush to where you brush to how hard you brush.

Design and Features

I've used Sonicare brushes for upwards of 10 years so I'm familiar with most of the brushes and brush heads, and the FlexCare is one step down from the top of the line brush, the DiamondClean (my day to day brush). To be honest, I'm disappointed that Philips added Bluetooth connectivity to the FlexCare instead of the DiamondClean because it doesn't have quite as many features (3 modes instead of 5) and the non-unibody design isn't as nice.

The FlexCare looks like your standard electric toothbrush, with a removable brush head that needs to be replaced every three months or so, a power button, and buttons for adjusting settings like intensity. Since brush heads are removable, you can share your FlexCare Connected base among several family members if you want to.


There are three cleaning modes: clean, a standard two-minute daily cleaning mode; white, a shorter mode designed to remove surface stains; and deep clean, a longer three-minute mode for a deeper clean. The main round button on the FlexCare turns it on and off, while the longer button is the one used to switch through the modes.

A third button at the bottom of the brush lets users select an intensity from one of three options: low, medium, and high. Users with sensitive gums and teeth will want to choose the low option, while the higher option will result in a better, quicker clean with up to 62,000 brush strokes a minute.

Unique to the FlexCare Platinum Connected is a set of sensors that are designed to work specifically with the app. There's a location sensor that relays where the brush is in your mouth, a pressure sensor that makes sure you're not applying too much pressure when you brush (which can damage your gums) and a scrubbing sensor to make sure you're not moving the brush too much (with a Sonicare, the brush does the work - you basically just hold it up to your teeth).

Sonicare ships the FlexCare Platinum Connected with two of its newest brush heads, the InterCare and the AdaptiveClean. Both of these brush heads are on the larger side compared to other Sonicare brush heads so they cover a lot of surface area. The InterCare brush is designed to reach more deeply between the teeth while the AdaptiveClean has flexible sides that are supposed to cover more of the tooth for a better clean.

Sonicare brush heads are supposed to be replaced every three months and cost somewhere around $10 to $15 per brush head, so that's an expense to be aware of when purchasing a toothbrush like the FlexCare Platinum Connected. Integrity of the brush head is important for better plaque removal than a manual toothbrush (Philips promises that its brushes remove as much as 10x more plaque).

Sound wise, the FlexCare Platinum Connected is louder than the DiamondClean but it isn't obnoxiously loud. It sounds like your average electric toothbrush.

The FlexCare Connected can be purchased with or without a UV sanitizer (the model with one is $20 more expensive) that can be used to sanitize brush heads. I've previously owned a UV sanitizer and while it works fine, I don't think it's an essential piece of equipment. You just stick your brush head in the container, shut the door, and turn on the light to kill germs.

It's simple enough, but there are bacteria in your mouth anyway that you can't UV sanitize and toothpaste is probably taking care of a lot of the lingering bacteria on the brush.

App

Sonicare's app isn't for tracking brushing habits over time, but for making sure you're brushing the right way in the moment, something I found to be a lot more useful than the over-time tracking feature in the Oral-B app designed for the Oral-B Bluetooth toothbrush.

The Sonicare brush connected seamlessly and quickly to my iPhone through the Sonicare app. Using the app is done by launching it before you turn on the brush for a daily brushing session. As soon as the brush turns on, the app displays a 3D model of a mouth and guides you through brushing each quadrant of your mouth. As you brush, the teeth in the 3D model go from yellow to white to denote progress, which is quite motivating.

Using the sensors in the brush, the app can vaguely tell where the brush is located in your mouth, so it's able to detect how long you spend brushing each area. With the "Clean" setting, it walks you through two minutes of brushing and then directs you to turn the brush on again for a touchup of all the areas where you didn't spend enough time, making sure everything is thoroughly clean. It's also able to detect too much brush movement and too much pressure, sending alerts through the app each time.

The FlexCare Platinum Connected's movement sensors are decent, but not infallible. The app can detect which side of your teeth you're brushing in each quadrant based on the way the brush is held, but if the app is directing you to brush the upper left quadrant and you do lower right, it can't tell the difference. You have to follow along with the app for it to be effective.
